White thread/spikey growing

[Marinereefiner]

Hello,

For several months now I have noticed that there are white strings almost worm like that are growing from the bottom of my blastomussa frag. They are growing out from it and the surrounding rock work. I have tried to research but cannot come up with a definitive answer to what it is. Assuming it is some kind filter feeder. Don’t think it is part of the blasto?

Any ideas? Doesn’t seem to be affecting the blastomussa at all.

Do they move, besides from the flow?

Nah, spikey and don’t move at all even in the flow.

I think it is some sort of tube worm growing out from under the blasto. or feather duster but I don’t see any feather heads.

Likely tube worms or sponges.
Beautiful blasto btw

(the little white coils are spirorbid tube worms - they are tiny feather dusters)

The white string things are starting to grow a lot faster. They a string like and flex when touched with fingers. Don’t seem to move much in the water movement. See updated photo of my blasto. Not sure if these killed on the of the polyps or some other unknown.

Anyone ID this for me please

Would like to share that the white growth is spreading. I have lost the blastomussa almost completely.
See the attached photo for the growth of these white critters. Don’t seem to be harmful unless this grows up inside of the coral.

Any help with confirming these ID on these critters

Yeah, those look like little feather duster worm tubes - they should be harmless, so I expect any issues would be caused by other things; based on how fast those have reproduced, I would wonder if the tank is struggling with nutrients or if that area of it is struggling with flow or something, but I don't know for sure.
